'- 7 which extend from the front of the runners 1 to the forward ends of said beams, as shown in the drawings, and by the shank bars 10 which extend upward from points near the front ends of said runners to connect by straps 12 to said beams and by brace bars extending upward from the rear ends of said runners 1 to the rear ends of said beams, and being so attached to said beams by means of the connections aforesaid as to be readily adjustable as to depth at which the knives attached to' the runners shall operate beneath the surface by means of the lever of the cultivator itself which raises and lowers the gang beams ordinarily.

Being so rigidly and firmly attached to the plow or gang beams of the cultivator and depending between the pair of beams and the device being placed astride the rows of plants, the wheels of the cultivator will run in the middle and between the rows of plants and thereby avoid the crushing of the plant-s by the wheels and the runners operating in the furrows beside the row of plants will tend to prevent lateral motion by sliding or slipping of the wheels of the cultivator and vice versa. The wheels will tend to hold the runners and knives and plows of the device in proper position relative to the row of plants and prevent crushing or plowing up of the plants in the row.

Beingv so attached by means of the bars and the straps to the beams of the cultivator, the knives can be controlled as to depth to which they operate in the soil and by means of the lever of the cultivator itself to which the device is attached can be kept underneath the surface of the soil in uneven ground, the knives cutting all the weeds and stirring the soil around the plants and between the rows.

By reason of the rigid attachment of the device to the beams of the cultivator, as above stated, it is especially adaptable to the cultivation of plants between lister furrows, the runners and sides of the fenders 21 preventing the loose soil stirred by the knives from covering the small plants to an undesired depth and at the same time by reason of such rigidity of the beams, the device is suitable for the cultivation of rows of plants that have been planted on a level, the wheels of the cultivator holding the device in proper position with relation to the rows of plants and preventing the device from any lateral motion which would tend to place the device or attachment out of proper position relative to the row of plants.

Because of the fixed attachment of the device tothe cultivator, its weight and its: con sequent pressure on the ground and the friction load by reason thereof are borne in great part by the wheels of the cultivator. The wheels of the cultivator and the runners 1 acting in the matter of carrying the load in a reciprocal manner, each to the other, and the load or draft is lessened and the horse power for drawing the cultivator and the device is decreased to a great extent.

Because of the attachment of the device to the beams 8 of the cultivator and the operators seat being on the cultivator itself, the operator is raised to a position which is further removed from the dust of the-field accompanying the use of the device and the operation thereof is rendered more sanitary and comfortable. Because of the connection of the device to the beams of the cultivator in the manner shown, the depth at which the knives and plows thereof operate beneath the surface is, by means of the lever of the cultivator itself, easily and readily controlled by the operator without stopping the machine or the operator leaving the seat, thereby rendering the device especially adaptable to the cultivation of rows of crops in uneven ground and in ground that is not uniform in friability without loss of time. Because of the rigidity of the device, the runners, knives, fenders and plowswill, by reason of the load being carried by the wheels of the cultivator, be easily held in proper position with. relation to the row of plants and the knives will stir the soil and cutall the Weeds between the rows and will not be shunted to one side or the other on account of contact of the knives with tough weeds or spots in the soil that are not easily friable. Due to the load being carried on the wheels of the cultivator and due to the reciprocal action of the runners and the wheels in carrying the friction load, the general motion of the whole machine is rendered steady and true and swaying motion is prevented and the burden of the draft is rendered steady and even. Also because of the rigidity of the device and the reciprocal action of the wheels of the cultivator and the runners in carrying the load and in holding the device in proper position, the device is especially adaptable to the cultivation of listed ground before planting, stirring the soil and cutting all weeds between the rows.

Further, by reason of the rigidity of the device relative to the cultivator and the consequent control of the depth at which the plows and knives run beneath the surface of the soil, the range of the use of the device with. relation to the size and height of the plants in the rows is increased, enabling the operator to use the device for the cultivation of plants of different sizes and heights. The shank bars are to be made of either round or fiat steel or iron to fit any and all different makes of Cultivators, while the runners 1 may be constructed of wood or metal which in either case are reinforced by the shoes or metal straps 6. However, should the runners 1 be constructed ofwood, the shoes 6 are consequently made of heavier from the beams for rigidly suspending the runners, draw bars attached to the forward ends of the beams and extending rearwardly and downwardly and in turn connecting with the forward ends of the runners to relieve rearward strain upon the suspension means, and adjustable yokes between and rigidly connecting the runners which, to-

gether with the suspension means, insures rigidity, thereby preventing lateral motion by slipping and sliding of the cultivator wheels, and vice versa.

2. The comb' ation with the structure in claim 1, of wear shoes secured to the sides of the runners immediately adjacent their lower longitudinal and forward edges, and knives secured tothe remote sides of the runners for operation beneath the surface of the soil for cutting weeds and stirring the soil around the plants and between the rows.

3. In an attachment for single or double row riding cultivators, the combination with beams carried by the cultivator and provided with straps on their remote sides, of shank bars connected to the beams by the straps and carrying spaced runners at their lower portions, the shank bars acting to prevent lateral mot-ion by sliding and slipping of the cultivator wheels and vice versa, arched yokes between and connecting the runners insuringtheir rigidity, whereby the prevention of said lateral motion is assured, thereby holding the runners operating in the furrows beside therow of plants, and draw bars operatively connected to the forward ends of said beams and extending rearwardly and downwardly and operatively connecting with the forward ends of said runners, thereby relieving rearward strain upon the shank bars and further insuring rigidity.

4;. The combination with the structure in claim 3, of wear shoes aflixedadjacent the end, and the bo-ttomedges of the runners, and knives. aflixed to the remote sides of the runners and extending rearwardly and laterally for operation beneath the soil and cuttings weeds and stirring the soil around the plants.

5. In an attachment for single or double row riding cultivators, the combination with parallel beams operativelymounted at their forward ends on the cultivator for fulcrum- ,ing movement, of rigidly spaced parallel runners rigidly suspended from the beams below and between them, whereby they may operate in the furrows beside the rows of plants, said runnersbeing structurally prevented from lateral motion by sliding or spaced fenders in the rear of and substantiall in alignment with the runners and operatlvely pivoted to the rear of the runners, means for holdlng the. fenders rigidly spaced, anda flexible anchor connected to the rear upper part of the cultivator and in turn operativelyconnected to the fenders, whereby as the cultivator frame lowers downwardly and forwardly, the fenders may tilt upwardly and whereby the cultivator frame moves upwardly and rearwardly and the beams tilt on their fulcrum, the

runners raise correspondingly with the beams and the fenders tilt downwardly.

In testimony whereof they atlii: their signatures.
